WILLIAM H. MARSH, OF SAN ANTONIO, TEXAS.

ACETYLENE-GAS TORCH.

SPECIFICATION forming part of Letters Patent No. 754,472, dated March 15, 1904.

Application filed October 1, 1903.

To all whom it may concern.-

Be it known that 1, WILLIAM H. MARSH, a citizen of the United States of America, and a resident of San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Acetylene Gas Torches, of which the following is a specification.

My invention relates to improvements in acetylene-gas torches in which the water percolates through a porous material into the carbid-chamber, thereby gradually generating the gas as required. V

The object of my invention is to furnish a simple torchlight especially for the use of lighting up hidden places for oiling locomotive-engines on the road. The present oiltorches are not satisfactory. I attain this object by the device illustrated in the accompanying drawings, in which Figure 1 is a vertical section of the torch, and Fig. 2 is a top view on line 00 w of Fig. 1.

The torch is of a cylindrical form and embodies two receptacles A and B, which are attached to each other by a screw-thread at C. The top of the receptacle A is closed by a cap D, in which is screwed a gas-burner E, as used for acetylene gas. The upper part of the receptacle A direct under the burner is filled with a layer of cotton F'and a layer of ashestos fiber G to purify the gas before it reaches the burner.

To prevent the dislocation of the cotton and asbestos by recharging the receptacle with carbid, a screen-bottom H is inserted into the receptacle A. The lower part of the receptacle A is filled with carbid I to a certain extent, leaving suflicient space for the carbid to expand when slaked. The receptacle A is then closed by a screen-bottom K.

The receptacle B is divided in two compartments by a partition L, which forms a valveseat, and which has in a circle four valve-holes N and in the center a hole through which Serial No. 175,329. (No model.)

the holes when the valve is on the seat. The lower compartment, which is the receptacle for the water, is closed by a bell-shaped bot-v tom M, having in the center a stufiingc-box Q, through which passes the end of the valvestem 0. On this end is screwed a push-button B after a coil-spring S is passed over them, whereby the valve is pressed against the seat.

For filling the compartment with water an inlet with a screw-stopper T is in the receptacleB near the bottom.

In the upper compartment of the receptacle B is inserted a cylinder U, having a screen top and bottom. The cylinder is filled with cotton or any other suitable porous material.

To operate the torch, hold it downward and press for a moment the button R and sufiicient water will be absorbed by the cotton or any other suitable absorbent in the cylinder U and percolate through the same, thereby moistening the carbid and gradually generating the gas as required. When the entire moisture is absorbed by the carbid, push the button R again.

Having fully described my invention, what Iclaim as my invention, and desire to secure by Letters Patent, is

In an acetylene-gas torch of the classdescribed a cylindrical receptacle A, a burner Escrewed in the top cap of the same, a screenbottom H for holding cotton and asbestos layers in place, a cylindrical receptacle. B, holding in its upper compartment a cylinder U, With screen top and bottom, containing cotton or other porous material, and the lower compartment having a valve P, on a valve-seat L, with four valve-holes N, in a circle, all set forth and described.

Signed at San Antonio, Texas, this 12th day of September, 1903.
